Whatever parts you're going to get now it will be obsolete in 4 years and useless in 8 (unless of course you plan to keep all the software as is, without any updates). On the present parts:you will need to upgrade the memory very soon, the hard disks are ridiculously small - 2 of 1TB is the minimum, the video card is way to feeble (i know that personally, i own one) - you need one at least from the 4xx gen if you don't want to replace it next year and the Windows is the wrong type - 64bit is the future.
Locate J8J1 next to the battery. Pins 9-15 are unused. Pins 12 and 14 are missing.
Pins 1 and 3 are for hard drive led.
Pins 5 and 7 are for Reset.
Pins 2 and 4 are Pwr Led.
Pins 4 and 6 are Power Switch.
New PC or old PC?
New motherboard or old motherboard?
New hard-drive or old hard-drive?
Check the ribbon-cable between the motherboard and the disk-drive, to make sure that both ends are seated correctly.
Turn the computer off. Unplug the AC power-cord.
Touch the hard-drive -- is it "warm" or "cold" ?
Cold means that it is not getting any power.
Remove the hard-drive. Look at the labels on it. Write-down the manufacturer, model-number, serial-number, and manufacture-date. Go to the manufacturer's web-site, and enter the serial-number, to see if the drive is still under warranty.
Hi there. Try clearing the cmos . move the plastic jumper the alternative position, power the pc up (Nothing will happen if you have it correct, then put it back in its original position and try to boot the machine again, don't forget to clean the memory as a precaution.
If you hear no beeps and the led lights, and the fans stay on after striping all the components from the motherboard except for the cpu, and power supply, you have either fried your motherboard or your cpu.
Its impossible to tell without more testing.
I'm sorry but you either need someone to test it or you can buy a new computer (thats what I did).
For about USD $300-$400 you can get a brand new computer with 500mbs of ram, 120gb hard drive and a 3 ghz cpu. If you look around you can get an even better deal.
